ABSTRACT:
An air induction system for an internal combustion engine featuring a throttle body and air cleaner assembly vibrationally isolated from the engine by a resilient air transmitting zip tube interconnecting the throttle body with the engine air intake manifold. The zip tube flexes to isolate the throttle body from engine vibrations and oscillations thereby eliminating a cause of throttle body fractures or looseness from its mounting. Furthermore, with such isolation, the throttle body can be readily formed from plastics and provide long service life. With the throttle body isolated, engine generated throttle pedal vibration is eliminated. Additionally with the remote location, throttle body and throttle plate coking and icing from recirculating exhaust gases is obviated. The throttle body and air cleaner assembly is supplied as a unit to augment vehicle assembly.
